GRAIN-DOOR FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 617,642, dated January 1o, idee. Applicant; nea may 6,1398. serais. 679,928. (No man.)

To all whom it may concern:

Be it known that I, BENJAMIN WATSON DAYIS, of Rock Springs, in the county of Sweetwater and State of Wyoming, have invented a new and Improved Grain-Door for Railway.l Cars, of which the following is a full, clear, and exact description. The object of the invention is to provide a new and improved door more especially de- -Io signed for use on railwaycars carrying grain and the like and arranged to permit of readily opening the door and holding it in an open position in the car completely out of the way, so as to give convenient access to the stored x5 grain when unloading thecar.

The invention consists 'of novel features and parts and combinations of the same, as will be fullydescribed hereinafter and then pointed out `in the claims. l

Reference is to be had to the accompanying drawings, forming'a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement as applied; Fig. 2 is a transverse section of the same'on the line 2 2 in Fig. 1, and

Fig. 3 is a sectional plan view of the same on thelinel 3 of Fig. 1.

The railway-oar A, of any approved con-` 3o struction, is provided on each side with the Y usual doorway B, adapted to be closed by an ordinary door-A. (Shown in an open position in Fig. 1.) vQn the jambs B' ofthe doorwayB are' secured vertically-disposed gnideways C, engagodby projecting sets of pins D Dion the `upper and lower sides of a grain-door D; adapted to normally rest on the ,110.617 fOf the car, 'as is plainly indicated in Fi land 2. The upper ends of the gudeways are curved inwardly, as at C', and terminate in horizontally-disposed guideways C, formed at their innerends with en elongated dro C",adapted "to be engaged by the uppermos .pins D' at the time the carfdoor is pushed into an uppermost position, as indicated in dotted lines at the left and in full'lines at the right in Fig.

I i 2. The upper ends of the jambs B' are formed 'with osets B, adapted to be engaged by and form rests for the pins D, so as to support 5o thedoor in a horizontal position when raised,

as indicated at the right in Fig. 2. lt will be tion of branch gnideways extending out-...F

main guidewaywith the branch guideway.

observed that the oisets B2 are located en` tirely without the main gudeways C C C, upon the outer side of guideways, and that the upper surfaces of the osets form a. por- 5.5

wardly from the main guideways, into which the pins D2 at the lower end of the doorD can be shifted after passing the junction of the `e Now it will be seen that by the arrange f ment described the door D 'can b e readily pushed upward, the pins D D3 travelinginv the guideways C, so that the uppermost pins D' finally pass over the rounded en'd C2. he -65` guidenntys [Eend inte the innermost the drops C, the doortben beingfpushedfoutl ward to-bring the pins Dz onto the offsets` 13.2,.. to hold the door `in an 'uppermost horizontal?? position, as indicated in full lines at'the 76 in'` Fig. 2. The doorwayA B is thus ,nnob structed and gives ready accessto thqcon; tents of the car. When it is desired fo close the doorway at the lower portion by the Se grain-door D, the operator first slides. the door "15 inward to bring the pins D into the c g11fvved.,` part C', and then lifts the forward end ofthe door to dsengage the pins D from the f C3, and then slides the doot` -outwardly'and downwardly, the pins D traveling along the Arounded portion C' and nally downv thejver-` tical guideway C and the piusDtraveHng along the gnideways 2 and. the parts C to the guidewa s C. The guideways C3 andtheir drops On the front edge of the grainfdoor Disare ranged a locking' device for fastening the' door` in a lower-most position,l said device consistiing of two bolts F F', fitted to slide in suitable 9o bearings on the said door and adapted' to en gage keepers B3, formed in the jamba B'. The inner eudsof the bolts, F F are pivotally` connected with a lever G at opposite sidesfofj v its fulcrum G', said lever being provided with 95 a handle (12 for conveniently swinging.the..H lev'er to move the bolts F F in or out of enfgagement with the keepers B. L, vi f The device is very simple and durable in construction, and the entire Aarrangement. can roc" be readily built into old cars now in use.. f

The door is always ready for use when are secured to transverse beams 5 E on the roof of the car, as shown in Fig. 1 2,

vented and forms a permanent fixture of the car, so that it cannot be left or forgotten at the station nor lost.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. The combination of the freine having :t door-opening and vertical guideways adjeeentthereto: seid guideways being,r continued at their upper ends by an approximately horizontztl portion, and offsets or supports located entirely without seid guideimys and on the outer eide thereof adjacent to the meetingpoint of the horizontal and vertical sectiors, and e door mounted to move in said guide- Weys and adapted to rest on seid offsets.

. The combination of the frame having e door-opening and vertical guideways :nlja

cent thereto, said guideways being continued at their upper ends by a curved portion and en approximately horizontal portion having e drop at its inner end, and oisets or supports located entirely without said guideways and 011 the outer side thereof adjacent to the curved portion, the upper s1. rface of said olfsets forming a portion of branch guideways extending'outwardly from the main guide- Ways, and :t door having projections mounted to move in said mein guideways and branch guidcweys.
